Embodiment 1

[0046] 1) Place the purification unit of the used glove box in the purification unit placement area;

[0047] 2) After the workstation control unit senses the purification unit, the heating regeneration element is started, and under the control of the control unit, the heating regeneration element is heated and pressurized, and the airflow entering the heating regeneration element is controlled , so that the purification unit is regenerated; the purification unit is regenerated under the method comprising the following steps, the heating and regeneration element is evacuated to 100 Pa, maintained for 30 minutes, and then heated to 250 ° C within 5 minutes and maintained for 1 hour, and then pressed Add 5% hydrogen-nitrogen mixed gas at 400ml / min for 40min, repeat the above process 5 times, then stop heating and vacuumize for 5 hours, and then fill it up to normal pressure.

Embodiment 2

[0049] The specific regeneration method is the same as that in Example 1, except that the purification unit is regenerated under the method comprising the following steps: vacuumize the heating regeneration element to 1000 Pa, maintain it for 60 minutes, and then heat it to 200°C within 10 minutes and maintain it 2h, then press 250ml / min to supplement 5% hydrogen-nitrogen mixed gas for 60min, cycle the above process 5 times, then stop heating and vacuumize for 5 hours, and supply the gas to normal pressure.

Embodiment 3

[0051] The specific regeneration method is the same as that in Example 1, except that the purification unit is regenerated under the method comprising the following steps: evacuate the heating regeneration element to 100 Pa, maintain it for 30 minutes, and then heat it to 250° C. within 5 minutes and maintain it 1h, then press 350ml / min to supplement 5% hydrogen-nitrogen mixed gas for 45min, cycle the above process 5 times, then stop heating and vacuumize for 5 hours, and supply the gas to normal pressure.

Abstract

The invention discloses an energy-saving and environment-friendly glove box workstation and a method for regeneration of glove box purification units. The workstation comprises a workstation body and further comprises a workstation control unit, wherein a heating regeneration element is arranged on the workstation body and comprises a plurality of purification unit placing areas used for placing glove box purification units; under the action of the workstation control unit, the heating regeneration element ensures regeneration of the glove box purification units in the purification unit placing areas. The method comprises the following steps: (1) glove box purification units which are used are placed in the purification unit placing areas; (2) after the workstation control unit induces the purification units, the heating regeneration unit is started and heated, pressurized or depressurized under control of the control unit, airflow entering the heating regeneration unit is controlled, and accordingly, regeneration of the purification units is realized.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and relates to a workstation and a regeneration method, in particular to an energy-saving and environment-friendly glove box workstation and a method for regenerating a glove box purification unit thereof. Background technique [0002] Glove boxes are widely used in high-tech research fields and manufacturing processes such as medicine, biology, chemical engineering, nuclear energy, lithium batteries, and machining. The glove box can not only provide an anhydrous and oxygen-free experimental environment for various scientific research and production, but also provide safety protection for scientific research workers, such as medical biological anti-bacteria and disease prevention, nuclear energy anti-radiation anti-leakage, and chemical and chemical anti-corrosion. Toxic gas and so on. [0003] At present, the glove box mainly includes a box body, a purification and deoxygenation ...
